Assign ICC Profile

Here we are going to assign the ICC profile you created to the IT8 film target you scanned. This will allow you to evaluate your initial IT8 target scan and determine if you need to adjust the RGB Exposure in Vuescan when scanning.

• To evaluate your IT8 target scan and determine if the RGB Exposure in Vuescan is correct, we will examine the first white box in the gradient at the bottom of the chart.

• Open the Info tab
• Zoom into the bottom left corner of the chart
• Select the Eyedropper Color Sampler Tool
• Click in the middle of the first white box to determine the RGB values

• The RGB values should be within the 240-250 range. Values closer to 255 are too high, and will cause highlight clipping. Values under 240 can cause the target to be under exposed.

• It is important that your IT8 scan is exposed properly. Increasing your IT8 scan to the highest exposure before clipping will produce the most shadow detail.

5. If your RGB values are not within the 240-250 range, repeat the process.

• In Vuescan, adjust your RGB Exposure value by +/-0.05 from the initial value you wrote down
• Rescan your IT8 film target
• Creating a new ICC profile
• Assign the profile your new IT8 scan and evaluate the RGB values.

About

My name is Ian Sheh, I am a film/digital photographer based Vancouver, Canada. I hope this site has helped you create better scans using Vuescan.

This process was created out of the need for better scans from Vuescan. With the help of many contributors and commenters, I believe we have found the best way to utilize Vuescan. If you would like to view the original post with all of the additional comments, you can find it here.

ICC Profiles

Pre-generated ICC film profiles are difficult to come by. Profiles are specific to scanners and film type. In an effort to make ICC film profiles more accessible, below are a few pre-generated profiles for particular scanners.

Film Presets

Film presets have become popular. The initial presets were created for mobile phones and digital photographers to bring some nostalgia to their images. As of late, there have been high-quality film presets created by companies who employ the best scanners and profiling equipment to create accurate film presets for digital images. Companies like Mastin Labs, and Totally Rad! are leading the way. These presets are a useful tool for the hybrid film/digital photographer who need their film and digital images colour-matched.
